An Ontario Provincial Police (OPP) officer has died after he was shot in Haldimand County while responding to a call, police say.

OPP Commissioner Thomas Carrique identified the officer Tuesday evening as Const. Grzegorz Pierzchala, who died "courageously serving in the line of duty."

"Our hearts are with his loved ones and all OPP members at this tragic time," wrote Carrique on Twitter.

OPP Sgt. Ed Sanchuk says a male and a female are in custody in connection with the fatal shooting.

He says no other suspects are outstanding, though he did not say whether any charges have been laid.

According to Sanchuk, Pierzchala responded to a call of a vehicle in a ditch around 2:40 p.m. at Indian Line and Concession 14, roughly 40 kilometres away from Hamilton, near Hagersville, Ont. The area is also home to Mississaugas of the Credit First Nation (MCFN) and next to Six Nations of the Grand River.

Upon arrival, Sanchuk says Pierzchala was shot. He was transported to hospital with life-threatening injuries.

OPP say Pierzchala was 28-years-old and died during his first year as a provincial police officer. 

"Greg was a phenomenal officer, great guy, great community member," said Sanchuk. He noted his family is asking for privacy at this time.

"He's going to be truly missed by everybody."

A male and a female were seen leaving the scene, police say.
